Hi everybody,
I'm trying to create an online status check for a standalone
application. Assuming the best (let alone a third party app) solution
would be to actually retrieve a file, this is what I have:
class Test{
private var online:Boolean;
private var onlineURL:String =
"http://www.laiverd.com/groundzero/online/online.txt";
// constructor
function Test() {
appIsOnline = checkOnline(); // return value from
checkOnline never arrives
}
// functions
public function checkOnline() {
var onlineCheck_lv:LoadVars = new LoadVars();
var success:Boolean;
onlineCheck_lv.onLoad = function(success) {
if (success) {
trace("success = " + success); // trace
is correct
return true;
} else {
trace("success = " + success); // trace
is correct
return false;
}
// delete success;
// delete this;
};
onlineCheck_lv.load(onlineURL + "?nocacheVar=" +
Math.random());
// probably some way of returning the onLoad event should appear here,
but how so that it is within the scope of the function?
}
// setters
function set appIsOnline(val:Boolean) {
online = val;
}
// getters
function get appIsOnline() {
return online;
}
}
The property 'online' never gets set using its setter appIsOnline. The
problem I think is somewhere in the fact that I am creating a new
instance of the LoadVars object of which 'succes' is a property. That
small part works. Question is; how do I get the value of 'success'
passed on to the property online using the setter appIsOnline. I've also
been trying to do things with onEnterFrame as the onLoad is
asynchronous, but couldn't get that to work either.
I am obviously missing some scoping knowledge, and as this has been
bothering me for a couple of hours now, I hope you can free me from
running in circles.
Thanks.
John
